WARPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,745, dated March 25, 1884.

Application filed July 11, 1883. (No model.)

To all whom it may concern..-

Be it known that I, GEORGE S. FOLLANS- BEE, of Boston, in the county of Suffolk, State of Massachusetts, have invented an Improvement in XVarping-Machines, of which the following description,in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention, relating to warping and beaming machines, has for its chief. object improvements in the construction and adjustment of the drop-wires.

One part of my invention consists in expanding springs and means to operate them, combined with a series of dents, a series of heads positively connected with the said dents,

and drop-wires pivoted to turn in the said heads fixed to the said dents, the latter being adapted to be moved toward or from each it other, according as the expanding springs are contracted or expanded, substantially as will be described.

Other features of my invention will be hereinafter specified, and particularly set forth in the claims at the end of this specification.

Figure'l represents in side elevation por tions of a warping and beaming machine embodying my invention; Fig. 2, a section on the dotted line 00 m, Fig. 1, the support for the other end of the vibrator being shown in dotted lines, it in practice being just like the support at the left of the said dotted line in Fig.1; Figs. 3 and 4, sectional detailsreferring to the drop-wires and their supports and the slotted heads and dents; Fig. 5, a detail more extended, showing my invention embodied in an apparatus having but one row of dropwires, the face of the box containing the usual expanding springs and screw being removed; Fig. 6, a cross-section ofFig. 5011 the dotted line a, the said Fig. 6 also showing, however, the vibrator-shaft with one set of arms; and Fig. 7- is a small diagram-like end View, to represent my improvements applied to a warping-machine of usual construction.

My present invention is incorporated with an apparatus such as shown in my application N 0. 78,808, filed December 8, 1882, andI have herein marked parts common to that application with like letters, and suchparts do not therefore need to be herein specifically described, or the way of moving them be fully shown. The parts common to that and this application are the vibrator or rock shaft 12 the cross-bar I), having flanges, as therein described,the lever (1 having roller-tappets, rod 6, bracket hi, and rod m. The parts so far described will be operated as in the said application.

The vibratorshaft I) (see Figs. 1 and 2) actuates two vibrators, A A, on arms A A, the said vibrators being adapted to strike the ends of any of the drop-wires B, which may dropinto horizontal position by reason of the breaking of a thread, and. the vibrator so arrested in its movement will effect the stopping of the machine, as described in the.

comb-box, D, has within it a right-and-leftthreaded screw, D, to which are applied two traveling, nuts, E, which, as shown in Figs. 1 and 2, are made to receive four pairs of usual expanding springs, E E E E, whereas ordinarily the said nut co-operates with but two pairs of expanding springs, as shown in Fig.

6. These expanding springs receive through.

them'the dents 2, which at their upper ends have attached to them slotted heads 3. A series of these dents having been inserted between the coils of the springs, and their heads having been placed side by side with their openings 5 (see Fig. 4) in line, the other open end,6,of the drop-wiresB are inserted into the slots of the said heads H, and the support 4. forthe said drop-wires is then inserted through the said heads and the open rear ends of the drop-wires, as shown best in Figs. 2, 5, and 6. As the pairs of springs areexpauded by turning the screw D* in the proper direction, the

dent-s are uniformly separated, causing the heads and the drop-wires therein to slide laterally'with relation tothe support 4, which servesas the pivot for each drop-wire, and,

besides serving as a pivot, the said support steadies the heads and dents and. prevents the latter from being lifted out of the comb-box.

Instead of the support 4 being made as a and lifts the drop-wires, and vice versa.

long rod, I may provide each head with a stout pin or pivot for the drop-wire to turn on.

To warp fine threads, there should be two rows of drop-wires, and it is an object to arrange them compactly. This I have done in Figs. 1 and 2, and in one comb-box, by enlarging the nuts E so that they may control expanding springs'at each side, and by doing this I am also enabled to work the screw and nuts more uniformly than were the expanding springs connected only with onehalf of it, as in Fig. 6.

In Figs. 1, 2. and 6 Ihave provided means for lifting the drop-wires automatically, such means consisting of a long bar, 14, mounted on arms 15, pivoted at 16. Moving either of the said bars longitudinally from the dotted to the full line position, Fig. 1, elevates the bar The lowest position of the bar 14 is governed by the arm 15, striking against a stop, 17. The rollers O O C serve as supporting-rollers for the threads. Both ends of the bar 14 are supported by a like lever or arm, 15.

I claim 1. The expanding springs and means to operate them, combined with a series of dents, a series of heads, 3, positively connected with the said dents,and drop-wires pivoted to turn in the heads fixed to the said dents, the said dents being adapted to be moved toward or from each otheraccording as the expanding springs are contracted or expanded, substantially as described.

2. The comb-box, the right-and-1eft-handthreaded screw,the nuts adapted to be actuated thereby, and two pairs of expanding springs at opposite sides of the said screw,combined with a series of dents held by the said springs, a series of heads positively connected with the saiddents,and with drop-wires pivoted to turn with relation to the said heads, substantially as described.

3. The dents 2 and the slotted head 3, rigidly attached to' it, combined with a dropwire pivoted in the said head, substantially as shown and described.

4. The comb-box and series of pivoted dropwires, combined with the bar 14 and its pivoted arms 15, to operate substantially as described.

In testimony whereof I have signed my name to this specification in 'the presenceof two subscribing witnesses.

GEORGE S. FOLLANSBEE.
